Two hundred and twenty boy*, 7 to 12 years oT j ^ t , were subjected ro a comprehensive
medical, anthropometric, and physiological evaluation to assess tin: prevalence of coronary
artery disease risk factors. These risk factors include obesity, blood lipids and lipoproteins,
blood glucose, blood pressure, cardiorespiratory fitness, and physical activity level. The
results of :his Study indicate that there are no significant age-related differences in total
cholesterol, triglycerides, LDL-cholcstcrol, HDL-G'cholesterol ratio, or blood glucose. No
significant hypertension was detested among the subjects, Using relative body fat, 15.6% of
the boys were considered obese. body fat percent showed significant inverse relationships
with cardiorespiratory fitness, HOL-ehok-slerol, HDL-Ccholestcrol ratio, and was related
positively to systolic tind diastolic blood pressures bur not to total cholesterol. Blood pressure
was not related to cholesterol or triglyceride levels. The findings of this study also showed
that 223% of the boys exceeded cholesterol level of 5.2 mmal/L.26,4% had triglyceride tev*j
above 1.4 mmol/L., 15.4% had a LDL-cholestcrol level above 3.4 mmol/L, and 4.0% had
HDL-cholestcrol below .96 mmol/L. Wc conclude that a considerable percentage of the
tested schoolchildren between the ages of 7 and 12 years have one or more coronary artery
disease risk factors.
